ALTERATIONS IN THE POPULATION OF LEUCOCYTES IN THE BLOOD OF A FRESHWATER FISH CLARIAS BATRACHUS (MAGUR) DUE TO INTOXICATION OF TWO ANIONIC SYNTHETIC DETERGENTS

摘要

The effects of two sub-lethal concentrations i.e. 1/4th and 1/8th fraction of 96 far LC_(50) of Detergent-A and Detergent-B (anionic synthetic detergents) were studied on leucocytic population in a freshwater fish Clarias batrachus. Percentage of thrombocytes and small lymphocytes, was found increased while large lymphocytes, raonocytes, neutrophils, eosinophils and basophils were found decreased at sub-lethal concentrations of both on all exposure periods. However, the changes were more significantin me blood of fishes when exposed to sublethal concentrations of Detergent-B man those of Detergent-A.
